Prince Naif Center for Dialysis, Riyadh.

The ABB i-bus® KNX DALI Gateway lighting control system has been successfully operating at the new Prince Naif Center for Dialysis in Riyadh, the capital of Saudi Arabia, since November 2011 when the center was officially opened.

Housed in a new purpose-built three-storey building with a floor space of around 5,000 square meters, the center has the capacity to provide lifesaving treatment for around 200 kidney patients every day.

Dialysis is a treatment for removing toxic waste and excess water from the blood of patients whose kidneys no longer function properly. Each treatment typically takes several hours and is performed three or more times a week. Without the treatment many patients would not survive.

Lighting is a significant element in the running costs and ambience of a medical center, due to the round-the-clock nature of medical services and the soothing effects that lighting can have on patients and staff.

The ABB lighting control system delivers significant returns on both counts by providing double-digit energy savings and by enabling the lighting intensity in each of the 48 dialysis rooms to be individually adjusted by patients during their long treatment sessions.
Staff and patients can control the lighting in each treatment room by using the Busch-Jaeger SmartTOUCH control panel. Busch-Jaeger is an ABB company.
Energy is saved by using presence detectors in stairwells, brightness sensors for the façade, gardens and external areas, and timers for parking areas – or a combination of all three where needed. The flexibility of the ABB i-bus technology enables it to be seamlessly integrated with the dialysis center’s building control system to create a truly smart building in which the lighting, climate and other automation systems are digitally monitored and controlled.

ABB i-bus is an open protocol system that uses both the KNX international standard for the control and monitoring of intelligent buildings and the DALI Gateway digital addressable lighting interface, which enables data to be transferred digitally between lighting devices and the network controllers.

This enables the ABB solution to deliver considerable energy savings for the dialysis center of as much as 40 percent compared to lighting control systems that use closed communication protocols.

ABB was selected by the center’s owner, the Ministry of Interior, on the strength of the energy savings achieved and the many ABB i-bus references in Saudi Arabia, the most recent of which is an award-winning installation for the 8 million square meter Princess Noura University - the largest university in Saudi Arabia and the largest women’s university in the world.
